Abstract: A process for oxidizing ethyl-substituted benzenes to benzene carboxylic acids in a solvent mixture consisting of acetic acid and water using a cobalt carboxylate and manganese carboxylate catalyst and maintaining the concentration of unreacted ethylsubstituted benzene in reaction mixture at a value of at least 5 percent by volume on a solvent-free basis.
